This incredible crystal was discovered by Wine Hardware on a buying trip to France. Wines taste better in these finely crafted wine glasses because of the 24% lead with Micro-Crystal Dispersion. A special process in the glass-blowing causes greater space between the molecules of the glass, leading to more surface area. This enhances the complex flavors and bouquet of the wine. Each glass is designed to direct the flow of wine to the “taste zone” that highlights each wines style and variety.
